How to spot a fault

Here, the Howgill Fells have been squashed up against the younger, limestone rocks of the Yorkshire Dales, sliding over the top of them, thereby creating the Dent Fault.

If you do happen to notice one of these in your garden, please let me know.

The Dent Fault was discovered by local lad, Adam Sedgwick, who went on to teach Charles Darwin geology at Cambridge University. He was a great geologist, but could never bring himself to accept his famous pupil's theory of evolution by means of Natural Selection.

I am stuck on the subject because I quite like this planet and would quite like our species' detrimental effect on it to be minimised. But we are a selfish species, so all talk of reducing our energy usage is a waste of time. We need a reliable means of generating lots of energy while putting as little CO2 into the atmosphere as possible. Nuclear energy is our only hope for achieving this.
